XP stands for "eX Princetonian". This
name was chosen because most participants (especially in the early
XPs) were students of Jeffrey D. Ullman at Princeton or visiting researchers
The numbering comes from the idea that the XP workshops were the seed
for the founding of the PODS conference.
By this logic, the first PODS
the second XP4, and thus, when an XP workshop was held in the
summer of 83 (after the second PODS) the "right" numbering was XP 4.5.
When another XP was held in 86 it had to be numbered between 7 and 8.
Since it was held later in the summer than XP 4.5, it became XP 7.52.
Information about the XP Workshops was contributed by
Henry F. Korth.
